Beware this new spear-phishing campaign that mirrors official spoofs Microsoft Exchange emails

    A new spear-phishing campaign has been discovered that uses spoof Microsoft Exchange emails to target Office 365 users. The well-coordinated attack has a broad range of targets but appears to be predominantly focused on Office 365 users within several key industries, including healthcare, insurance, financial services, and manufacturing.

    Security researchers at email security platform IRONSCALES discovered the attack after finding that almost 100 of its customers were being targeted. The attack employs a sophisticated domain spoofing technique that makes it difficult to determine whether the phishing email is genuine or not.
